SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 256,164, dated April 11, 1882.

Application file d February 20, 1882. (No model.)

To all whom it may concern Be it known that 1, JOHN W. REGAN, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Snap- Hooks, of which the following description, in connection with the accompanying drawings, is a. specification.

Thisinvention in snap-hooks relates to means for closing the tongue of the snap; and my inventionconsists in a snap-hook having a pivoted tongue provided with a spring positively connected with the tongue at one end and left free at its other end, the said spring as the tongue is moved about its pivot sliding in a groove in the body of the snap-hook, the said springbeing flexed or bentand partially wound about the tongue and its fulcrum each time the tongue is turned about its fulcrum or pivot to permit the passage of a ring into or from the hooked part of the body of the snap-hook.

Figure 1 represents in front view a snaphook embodying my invention; Fig. 2, a side elevation thereof partially broken out to show the construction of the tongue and its connected spring lying in a groove made in the body of the snap-hook; and Fig. 3 shows the tongue removed with its connected spring in its normal position. The body a of the snap-hook may be of any usual shape. I have shown it as provided atone end with the usual strap-receiving eye, a and at its other end with the hook (i The body part a of the snap-hookis grooved, as shown in Fig. 2, to receive the tongue I), which is held by the pivot W. The tongue has a heel,-

b and is shown slotted near the heel to receive one end of the steel spring 0, the free end of which'is placed in the groove made in the body part of the snap-hook. The spring .0, by its action against the body of the snapo hook, normally keeps the heel b of the tongue extended across the opening leading into the space outlined by or within the hook part (L as shown in Fig.2. When the tongue is moved in the direction of the arrow. near it in Fig. 2, the end ofthe spring connected with the tongue, the free end of the said spring during such operation is drawn toward the pivot I) of the tongue; but as soon as the tongue is released from pressure the said spring, in its effort to resume a straight line or its normal position, quickly turns the tongue, bringing its heel against the shank of the snap-hook, which arrests the further movement of the tongue.

In the hook herein shown the tongue, when closed, is made to occupy a position nearly at right angles to the end a of the hook, and has a movement of about ninety degrees aboutits pivot b Such movement of theton guerequires a long flexible spring, one that will bend readily, and which, as the tongue is turned, bends and curves about the pivot b I claim- The combination, with the body of the snaphook, of the pivoted tongue I), having the heel I) and curved surface 3, and the spring 0, con-. nected at one end with the tongue near its pivot and adapted to be wound about the curved part 3 of the tongue and its pivot, all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN W. REGAN.
